W. GIBSON. HORSESHOE MACHINE.

No. 3,392. Patented Dec. 27, 1843.

WM. GIBSON, OF TROY, NEIV YORK.

MACHINE For. T E MANUFACTURE or HORSESHOES.

Specification of Letters Patent No.

To all whom z'imay concern Be it knownthat-I, IVILLIAM GIBSON, of the city of Troy, in the county. of Rensselaer and State of New York, have invented a new and useful Manner of Constructing Machinery for the Manufacturing of Horseshoes; and I do hereby declare that the following is a full and exact description thereof.

In the accompanying drawing Figure 1, is a representation in perspective of the ma chine by which the bar or iron from which the shoe is to be made is to be out ofi, upset edgewise, creased, and in part punched for the nail holes. A, A, is the main frame, or bed, of the machine which I make of cast iron, and which may be about three feet long and two feet wide, more or less.

B, B, is a stationary die fixed firmly upon the front of themachine, and between the inner end of which, and a movabledie, the

iron bar is to be pressed and upset edgewise. C, C is the movable die whlch is held in the die box D, D, and is made to vibrate back and forth by the action of a cam on the main driving shaft. The die C, C, may be made to slide back. and forth in grooves in the sides of the bed piece A, A; but I prefer to allow it to work on centers, for which purpose I extend hangers or arms, down from the under side of the die box D, D, at each end; one of thesearms is shown at E, with its center, or joint pin, at a. The die C, C, I make concave on its front edge, so

as to upset the ends of the iron which is I gripped between it and the die B, B, and to give to it the proper form widthwise. The concavity of the die C. C. and the amount of the consequent upsetting of the iron may be regulated at pleasure.

F, F, is abar which is jointed to the die box D, at F, and at its opposite end it bears against a vibratingarm G, working in a joint pin at its lower end. The arm G, is acted upon by a cam H, 011 the main shaft I, I, of the machine. The cam H, is circular at the part marked H, H, so as to'holdthe dieC, C, stationary, while the iron isbeing creased and punched; but at the part II, it is so formed as to allow the die to retreat when the creasing is completed, which it does by the action of a spring.

J, J, is the creasing and punching head which has on it two creasers and punchers 7), b, that are. brought down upon the iron while it is gripped between the dies B and 3,392, dated Dece1nber27, 1843.

C. that 1s hung on centers at L, L, and it is raised and lowered at the proper time by the cam IM, on the maindriving shaft.- N, is I a pushing rod orclearef, for removing the iron after it has been creased and punched; this may be operated by a crank c, on the end of the shaft I, as shown in the drawing, In using this machine the iron is fed in at O, in front of the. stationary die B, B, and rests on the bed of said die; as the die C, C, approaches it, the bar is cut off by the steel cutters (Z, and e; the dies B, and C, then grip and upset it, after which the creasing and punching head is brought down, and on the raising of this the iron is pushed 05 by the rod N, and is ready to be acted on by the bendingmachine, to be now described. I Fig. 2, is a perspective view ofthe bendingwmachine, and Figs. 3 and 4:, are parts of the under side thereof.

The head J, is attached to a lever K, K, I

The main frame, or bed P, P, of this machine may be like that marked A, A, Fig. 1. Q, Q, is a double rack made fast to the bed P, P, and It, R, is a sliding table which by means of a pitman S, and a crank T, on the driving shaft T, T, is made to traverse back and forth on ledges or grooves formed in the frame, or bed P, P. The table R, carries two wheels U, U, which gear into the double rack Q. The gudgeons of these wheels enter the table R, and are connected at top by the bridle V.

On the under side of the double rack is the former, IV, Figs. 3, and 4, which is made fast to it and determines the form of the I adjustable gage pieces f, f, at the time when said table is nearest to the driving shaft, T; the former being so situated on the under side of the rack Q, as that the piece of iron to be bent will be then just in front of it. As the driving shaft revolves, a cam Y, fixed upon 1t, will force forward a sliding bar Z, wh ch will press the piece of iron to be bent against the former IV,

and as the table R, recedes fro-m the driving shaft the benders X, X, will, by the revolue tion of the wheels U,U, be brought into action and complete the, bending during 'quired shape.

this operation the iron is confined between the table and the recess 9, g, on the former, and will be thus made to assume the re- WVhen removed from the table the punching of the nail holes through the shoe may be completed by means of the apparatus shown at Fig. 5, where h, is a punch, and 2', a bed, or die, on which the shoe may be held by hand; the punch being forced down by a cam j, on a revolving shaft, and raised by a spring 70, in a manner which does not require further description.

Having thus fully described the nature and operation of my machinery for manufacturing horseshoes, what I claim therein as new, and desire to secure by Letters Patent, is

1. The combination and arrangement of the parts concerned in the cutting off, the gripping, and the creasing and punching so that these operations shall be performed by the cutters (Z, 6, the dies C, B, and the creasers and punchers b, b, all operating as herein set forth.

2. I claim the manner of combining and arranging the respective parts of the apparatus for bending the shoe, as above described, said apparatus consisting of the stationary double rack, with the former on its under side, the sliding table, the two cogwheels with their benders, and the sliding bar by which the piece is held against-the former, the whole apparatus being constructed and operating substantially as herein set forth; not intending, however, to limit myself by this claim to the exact form of the respective parts as herein made known and represented, but to vary these as I may deem expedient, while I attain the same end by equivalent means.

WILLIAM GIBSON.
